angular velocity  
The rate of change of an angle associated with an object with respect to some reference point. For example, the average angular velocity of an object moving around a central reference point once every second is 2π radians per second; the Earth spins around its axis with an angular velocity of 2π radians per day. Also called angular frequency.
